From f093c388ef8ceff605f267ae9bc212ad98543ce6 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Tue, 12 Jun 2012 16:25:01 -0300 Subject: [PATCH] [media] dvb_usb_v2: use pointers to properties Use pointers to properties as device and adapter properties are constant. No need to embed and copy those structures.
